HEEL-MAILING .ACHINE.

SPECIFICATION forming part of Letters Patent No. 329,079, dated @otober27, 1885.

Application filed January 13, 18F5. Serial No. 152,725. (No model.) i

To aZZ whom it may concern:

Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in the countyof Middlescx and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Heel Nailing Machines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

The invention is an improvement upon that described in my applicationfor Letters Patent filed August 4., 188 i, Serial N o. 139, 595, and itrelates especially to the part of the machine therein described formaking the heelnails. In said application there is described awire-feeding device and carrier which severs the nail-blank from the endof the wire and carries it to a driver, and a driver, not for drivingthe nails, but for moving them from the throat of the carrier andmachine into a distributor. This construction necessitates quite anaccurate fitting of parts and a nice adjustment of the timing of themachine, in order that the nail may be severed, pointed, and fed to thedriver at the proper time, and as the driver is obliged to bercciprocated in the carrier-block it is obvious that the carrier blockmust continue stationary while this movement takes place, so that itleaves a comparatively small part of the revolution of the machine forthe operation of the cutters and the feeding of the nail by the carrierfrom the end of the wire to the line of the driver. By my presentinvention I dispense with the driver and parts for operating it, and useonly the wire-feeding devices and the reciprocating pointing device,which are in the form of cutters, as hereinafter explained. By thisarrangement the nail is severed and the Wire pointed by oneoperationthat is, the first movement of the severing device points theend of the wire. It is then fed forward anail length, and the nextmovement of the pointing mechanism seversa nail and points the next onein order. The nail which is severed either drops into the distributer oris moved therefrom upon the next feeding of the wire.

By this construction I am also enabled to obtain, without varying thecutter, varying lengths of nails, because the length of, the nail willdepend entirely upon the feed, and the feed is variable, as described insaid application;

ing my invention. Fig. 2 is a vertical sec tion through thecutter-blocks and cutters. Fig. 3 is a vertical section upon the dottedline of Fig. 2, with a section of the nail-distributer. Fig. 4 is a viewin plan below the dotted line it a: of Fig. 3. Fig. 5 is a perspectiveView of the cutter. Fig. 6 is a perspective view of one of thecutter-blocks, and Fig. 7 is a view in horizontal section of aburrcutter. Fig. 8 is a rear elevation of a portion of the heel-nailingmachine, showing my improved nail making and feeding machine and aportion of the heel-nailing machine. Fig. 9 is a view, partin horizontalsection and part in plan, on and below the line an x of Fig. 1.

WVhile all the devices hereinafter enumerated, with the exception of theparts which relate to the feeding, pointing, and severing of thewire,have been described in prior patents and applications, hereinafterspecifically referred to, I will briefly mention the parts and therelation which they bear to each other, in order that the object of theinvention may be better understood.

1 is a reciprocating cross-head. the revolving head 2. 3 is a templet,which is moved automatically into and out of position by the lever 4,operated by a cam, as described in the patent to me, No. 290,109, datedDecember 11, 1883. (Not shown.)

5 is the nail-carrier. It is moved by a lever, 6, operated bya cam, asdescribed in my said patent, and as described in my application filedJuly 17, 188%, Serial No. 137,980. It is moved from a position under thenailholder 7 to a position from whence its nails may be fed to thetcmplet when in operative position beneath the revolving head, as shownin Fig. 1.

8 is the disk, having holes circularly arranged and at auniform distanceapart, which are connected by tubes 9 with holes in the It carriesReferring to the drawings, Figure 1 shows a portion of a heel-attachingmachine containnail-holder 7. The holes in the nail-holder plate areclosed by the thin bottom plate, 10,

which is moved to open the holes by the pin 11 on the nail-holder 5, andis closed automatically by a spring. (Not shown.) The disk 8 is alsoconnected with thenail'holder 7 by a post, 12, so that the nail-holderand the disk may be simultaneously revolved. There is attached to thedisk the ratchet-wheel 13, by means of which and the pawl 14 at the endof the lever 15, and the cam 1.6 upon the shaft 17 the disk is revolvedintermittingly to bring the holes successively in line with the throatof the machine, as shown in Fig. 3. The wire is fed to the blockcontaining the feedway, hereinafter described, between the guide-rolls18, by the feed-roll 19, which is on the shaft 17, andthe roll 20, whichis movable in relation to the roll19, and is carried or supported by thespring-arm 21, which at intervals in the revolution of the shaft 17 iscaused to be moved outward to disengage the feed-roll 20 and the pinion22, which it carries, from the feed-roll19 and its pinion. A portiononly of the feed-roll 19 is represented in Fig. 1. The arm 21 isprovided with this movement by means of the wedge-block 23, which isoscillated by the cam 24 and lever 25, (see Figs. 8 and- 9;) and thewedge-block is also movable laterally or horizontally at a right angleto the line of its oscillation by means of the lever or arm 26, pivotedat 27,and connected with the oscillating bar 28, carrying the wedge 23.The time that the movable feed-roll is in contact with the stationaryfeedroll is varied according to the position which the wedge-block 23bears to the end of the arm 21. The wedge-block is so shaped that whenmoved by the handle or arm 26 in one direction it willcause, upon itsoscillation; the arm 21 to be held away or stationarylonger than whenmoved in the opposite direction; and when it is so moved, of course theextent of wire fed is less than when the block is moved, so as not tohold the feed-roll 20 off from the feed-roll 19 so long. It will thus beseen that by varying or adjusting the feed the extent or length of wirefed to the severing and pointing mechanism,hereinafter speci fied may begreatly varied, and that therefore nails of anylength within reasonablelimits may be made. I do not. however, claim the mechanism hereindescribed for adjusting the feed, and reference to the patent to ErastusWoodward and Horace WVeeks, No. 301,464, dated July 1, 1884, is

made for a fuller description of the construction of the device. Thehandle, arm, orlever 26, which operates the device for varying the feed,is locked to the bracket'29 by the screw 30.

The block, hereinafter referred to, for carrying or supporting thecutters is reciprocated by means of the lever 31, pivoted at 32, and thecam-groove 33 in the camdisk 34 on the main shaft 17.

Thus far the mechanism described does not vary in any material respectfrom that already described in the various patents and pendingapplications already referred to or hereinafter mentioned.

I will now describe the especial devices which comprise my invention,and whereby I am enabled to make and deliver a nail without the use of atransferring device or a driver.

A is a block having a hole, a, which forms the feedway through which thewire is moved by the action of the feed-rolls 19 20. This block has onits lower surface the V-shaped projection a through which the feedwayextends. Below this block A is another block, B, in which is a hole incontinuation of the feedway. Arranged to be reciprocated between theseblocks is the cutter O, which is shaped to have pointing blades orcutting edges 0, which preferably are V'shaped, and the severing-cutterc, which is horizontal or straight and below the V-shaped cutters. Thesecutters are carried by the reciprocating block a, upon which they areformed, or to which they are attached by means of bolts or screws, andthe block is reciprocated by means of a cam and connecting mechanism, asabove de cribed, and described in said application and in Patents Nos.225,527 and 301,464, to which reference is made.

In lieu of the cutters there may be used a cutting device havingcutting-surface d,which is in the nature of'a burr; and when this form.of cutter is used it may be given 'a longer stroke than is provided theother cutter.

The feed-rolls 19 20 may be operated in the manner described in my saidapplication, and the adjustment of the feed may be obtained by mechanismshown in said Patent N 0. 225,527, or by that shown in said Patent No.301,464. It is immaterial, for the purposes of this invention, however,how the wire is fed, or how the length of the feed is varied, as thereare many well-known ways, in addition to those above mentioned, foraccomplishing this purpose. I would state, however, that it is desirablethat the wire-feed rolls should be located quite near the upper block,A.

I do not of course confine myself to the means for reciprocating thecutters herein de scribed, as any equivalent means may be employed.

It will be seen from what I have already stated that the wire from whichthe nails are formed is fed by the feed-rolls which govern the length ofthe nail to the cutters; that the end of the wire is first brought inline with thecutters and pointed; that the wire is then fed by thefeed-rolls to the position shown in Figs. 2 and 3, and the cutters thenreciprocated past the wire, and the portion of the wire which is belowthe cutter is severed, thereby forming a complete nail, while at thesame time the point of the next nail to be cut off is formed, and thechips or pieces severed from the wire in forming the point are thrownout of the machine through the opening to the space in which the cuttersmove, the cutters having a sufficient movement to carry the chipssevered from the wire away from the same to the end of the passage orspace in which they reciprocate, and so that they are expelled from thepassage and fall therefrom to the ground, or to any suitable placeprepared to receive them. It will further be seen that the wire duringthe pointing operation is substantially supported against the thrust ofthe cutters by the block A, its projection a and for a portion of themovement of the cutters by the block B; and it will be seen, also, thatvariations in the length of the nails may be had without making anychange, in the machine by the lever 26. If the gage of the wire shouldbe materially changed, it would then of course be necessary to changethe blocks and cutter for others of the proper gage; and if it should bedesirable to make a longer or shorter bevel to the point of the nail,then the cutting tool and one of the blocks are removed and otherssubstituted. The nails thus formed either drop or are forced by the feedof the wire through the throat of the machine into the distributer, andthe dis tributer which I prefer to use is like that shown in myapplication for patent above referred to, and is operated by means of aratchet, pawl, and cam, substantially as described in said application,or in any other suitable way; and it is of course unnecessary to furtherdescribe the operation of this portion of the invention here, it beingsufficient to say that the distributer is arranged to receive the nailsone by one from the throat of the machine, and to discharge them in theholder, from which they are automatically taken by the carrier of thenail-machine and fed automatically to a position from which they areautomatically driven by the drivers, as described in my saidapplication. The time of the carrier, however, must be such that thereshall always be a hole in position to receive the nail just before ithas been severed, which hole must remain in position until after thenext feeding of the wire, in order that if the nail previously cut shallhave lodged in the throat of the machine it may be removed therefrom bythe next feeding of the wire; and in order to give as much time aspossible for the feed of the distributer it will be desirable to arrangethe feed so that it shall operate immediately after the cutters havewithdrawn upon their backward movement from the feedway.

It will be observed that this nailmaking feeding and distributing deviceis very simple; that it comprises only a wire-feeding device, thereciprocating pointing device, and the distribnter; and I would here saythat although I prefer the construction of distributer herein describedand the method of its operation, I do not confine myself to its use, butmay use any other equivalent device for receiving the nails from thethroat of the machine and delivering them in proper order in thenail-holder. Of course it is desirablethat the machine shall beautomatically started and stopped; but I need not describe the mechanismfor so doing, as it is fully described in my application for patentabove referred to. It will be noticed, also, that I am enabled by thisimprovement to do away with the driver for forcing the nails into thedistributer, the cam and spring for operating it, of the machinedescribed in my said application, and to make one throat answer thepurposes of the two described in said application, and also to do awaywith the transferring of the nail from one point to another-an operationwhich requires a very delicate adjustment of parts to provide for thenecessary accurate feeding. If desired, one of the cutters may belocated slightly in advance of the other, so that one side of the pointis formed before the other.

This construction makes the work of the die easier and requires lesspower.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In a heel-nailing machine,the combination of the stationary block A, having the feed way a, thestationary block B, having a throat in continuation of the feedway a,and the reciprocating pointing and severing cutters 0, adapted to bereciprocated between the blocks and across the feedway, allsubstantially as and for the purposes described.
